TENSION DEVICE FOR LOOM-SHUTTLES.

SPECIFICATION forming part of Letters Patent No. 492,395, dated February28, 1893.

Application filed May 2, 1892. Serial in). 431,509 (No model.)

To all whom it may concern.-

Be it known that we, JOHN B. FAISANT and JOSEPH EICHER, citizens of theUnited States, residing at Paterson, county of Passaic, and State of NewJersey, have invented certain new and useful Improvements in TensionDevices for Loom-Shuttles; and we do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon,which form a part of thisspecification.

The object of our invention is to provide a thread tension device forloom shuttles, simple and durable in construction and easily attachableto the various shuttles generally used in the trade.

The invention consists in the improved and peculiarly constructed threadtension device for shuttles, in the connection and combination of thesame with the shuttle body, substantially as will be hereinafter morefully described and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several views,Figure 1. is a top plan View of a shuttle, with our improved tensiondevice secured thereto, part of the shuttle body being shown in section,the tension device being in its normal position. Fig. 2. is a similarenlarged View of that end of the shuttle, in which the tension device isarranged, the latter being shown in a raised position, and Figs. 3, 4and 5 are enlarged detail views of the tension device.

In the drawings a represents a shuttle body of the ordinaryconstruction, provided with the recess or groove b, in one end, in whichis arranged and fulcrumed on the pin 0- the thread tension device 61.The said tension device consists of a Wire, of suitable length, bent atits center to forma loop 72, and at right angles thereto, and at eachside of said loop, a series of circular coils g, the latter beingadapted to form the bearing for the tension device (on pin 0). The freeends of said coils are twisted, as shown at f, and bent into loops ealternately; said loops are at right angles to the twists, and thelatter at right angles to the coils g, as clearly shown in Figs. 3 and4. As can be seen from the drawings, said series of coils (g) will formasubstantial and strong bearing on the pin 0. in anydesired many anelastic band (or spring) 1', adapted to hold the tension device in itsnormal position. Within the groove 5 is arranged diagonally a series ofpins 70. The thread passes over said pins and through the loops ealternately.

In operation, the tension device, with its wire loops 6 engaging thethread,turns freely on pin a, in a plane at right angles to said pin,and is controlled by the elastic band As the wire coils g form a widebearing on the pin all lateral motion of the tension deviceiseliminated, as will be manifest.

By our improved tention device, a uniform strain is exerted on thethread, and thus breakage or tearing of the latter is entirelyprevented.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-- A tension device for shuttles consistingof a single piece of wire having a double twisted shank f, tension loops6 integral with said shank and depending at right angles therefrom, acoiled sleeve 9, integral with the shank and adapted to slip over thepin 0 of the shuttle, and a looped arm h integral with the sleeve g andband 2', engaging the said arm h and the pins 7c, in the shuttle body,substantially as described.

In testimony that we claim the foregoing we have hereunto set our handsthis 19th day of April, 1892.
